using loops in stored procedures in sql server

Question

i have a stored procedure with 5 parameters.

@1,@2,@3,@4,@5

Five Columns

@a,@b,@c,@d,@e

One of them is of string types(@a) which contains "N" number of numeric values separated by coma(,).

ex:

@a= '1,2,3,4,5,6'
@b='a'
@c='f'
@d='g'
@e='h'

My requirement is to insert "N" number of rows .

The value of rest four parameter's will remain same for every row whereas the value of @a parameter will be fetched by splitting @a.

The table will look like the attached file

Answer 1

create table testtable(a int, b char, c char, d char, e char)
go

declare @a varchar(20)= '1,2,3,4,5,6,7,8,9'
declare @b varchar(20)='a'
declare @c varchar(20)='f'
declare @d varchar(20)='g'
declare @e varchar(20)='h' 

INSERT testtable(a,b,c,d,e)
SELECT t.c.value('.', 'VARCHAR(2000)'), @b, @c, @d, @e
FROM (
    SELECT x = CAST('<t>' + 
        REPLACE(@a, ',', '</t><t>') + '</t>' AS XML)
) a
CROSS APPLY x.nodes('/t') t(c)

select * from testtable
